The reason why I’ve picked such two visualizations is because, at a glance, they looked pretty cool and profound, and both of them are very interesting ones for me
For the first one, the Musicovery, it provides a two-dimensional plane to represent two different aspects of the music in the library: mood, either a dark or a positive one, and the pace, either an energetic or calm one, of the music. Besides, they assigned some color to the music to represent the genre of it. The most interesting feature is that, by clicking on the places that represents different combinations of mood and pace, it would shows up a list of music that best represent such combination. Just as its name shows, it could help the user discover new music.
The second one is a static visualization about Oscar winning actors. It shows the directors of the movies in which the actors get their prize for, and other non-Oscar winning actors that have worked with the directors. Interestingly, it is somehow a tree diagram: with the very top as the Oscar-winning movie, followed by their directors, Oscar-winning actors, and actors worked with them. As aforementioned, it seems to be very beautiful and cool visualization. But nonetheless, it sufficiently demonstrate the question that motivate this visualization: the relationship was between directors, Oscar winning actors and non-Oscar winning actors to see if they could find patterns in who actors work with. As the figure clearly shows, that only few of the outermost names have lots of connections with the inner names. However, unlike the pervious one, where the viewer, this one only serves for its purpose, and it is very hard to view it in another perspective; whereas the first one, as one could click on somewhere to get a detailed music that represents the combination of mood and pace, different aspects could be obtained from it, such as how rock spread on the mood-pace plane, or how is the popularity trend of different music in different time. Also, its main aim is to help user to explore the data: the music, wheras the first one is aming to provide the relationship between Oscar prize and the directors and actors.
